ELECTRICAL SWITCH APPARATUS.

SPECIFICATION forming part of Letters Patent No. 624,904, dated May 16, 1899.

Application filed October 15, 1898- Serial No- 693,624. (No model.)

To aZZ whom zit may concern:

Be it known that 1, WILLIAM F. BOSSERT, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Electrical Switch Apparatus and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in lo the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention is designed to increase the conductivity of electrical switch apparatus, to reduce the number of parts and joints of such appliances, to diminish the number of contact-surfaces, to economize in material and labor, and to improve the general construction of panel, distributing, and switchboard work, whereby all known advantages are combined in a single organization,together with a saving of material and time.

In electric switch apparatus comprising crossing bars representing main and branch conductors electrical connection is established between such as are intended to be coupled by interposed blocks or bridge-pieces, independent fastenings being required to secure the blocks to the respective conductorbars. Such construction necessarily entails expense in labor and material in the formation of the many joints, and the latter offer greater resistance to the passage of the electrical fluid than continuous conductors.

In accordance with this invention the crossing conductor-bars are deflected, offset, or bent at the points of crossing required to be electrically connected, so as to admit of their juncture or union without the interposition of blocks, bridge-pieces, and the like.

The invention will be more fully set forth hereinafter, reference being had to the accompanying drawings, in which Figure 1 is a plan view of an electrical switchboard constructed in accordance with and embodying the essential features of the invention. Fig. 2 is a detail section on the 50 line 2 2 of'Fig. 1. Fig. 3 is a sectional detail on the line 3 3 of Fig. 1. Fig. 4 is a section on the line 4 i of Fig. 1. Fig. 5 is a section on the line 5 5 of Fig. 1. Fig. 6 is a modification.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The switchboard illustrated is of ordinary appliance and operation and comprises the base 1, upon which the Working parts are mounted, main conductors 2, branch conductors 3, and switch-levers i. The number of the conductors and their relative arrangement and connection will depend upon the character of the work and the range and scope of the apparatus. The main and branch conductors cross, and at such points of crossing where it is required to electrically connect them a conductor is bent, offset, or deflected, as shown at 5 in the several detail views, sufficiently 7o far to bring the two conductors into close contact.

Fig. 2 shows a construction in which the branch conductor 3 extends upon each side of the main conductor, the offset part 5 being in the form of a loop. Fig. 3 illustrates the arrangement when the branch conductor extends upon one side of the main conductor only. In both forms the conductors are positively connected by means of fastenings, as screws 6, to prevent accidental separation.

Figs. 4 and 5 illustrate the terminal offsets at the ends of the conductors, whereby they are broughtto the plane of the board, thereby obviating the provision of blocks and strips, as generally required in the construction of this class of electrical apparatus.

Fig. 6 shows the conductor 2 offset a distance corresponding to the thickness of the conductor 3.

The several conductor-bars are secured at their outer terminals only to the base and do not interlace. Hence any bar of the appliance can readily be displaced for any purpose, when required, without disturbing the re- 5 maining bars.

It is contemplated to embody the invention in all electrical apparatus employing crossing conductors to the end that the construction may be simplified, the cost of material and la- :00 bor lessened, and the conductivity increased. Hence it is to be understood that in adapting the invention to meet any special requirement changes in form, proportion, and the minor details of construction may be resorted to without departing from the spirit or scope of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a device of the class described, the combination with a base of a main conductor formed integral and having its ends bent downwardly and secured to the base, that portion intermediate the downwardly-bent ends being separated from the base by an interspace, and a branch conductor formed integral, passed through said interspace and having an upwardly-projecting portion engaging the main conductor.

In a device of the class described, the

combination with a base, of a plurality of parallel main conductors, each formed integral and having its ends bent downwardly and secured to the base, that portion intermediate the downwardly-bent ends being separated from the base by an interspace, and a plurality of branch conductors passed between the main conductors and the base, each of said branch conductors being formed integral and having an upwardly-extending portion engaging its respective main conductor, whereby the body of each branch conductor will lie below the plane of the main conductors.

In testimony whereof I affix my signature in presence of two witnesses.
